As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (est. 1998) proudly presents our Standard Compliant Railway Sleeper Dowel Pin — a critical component for secure and durable track fastening. Designed to meet international railway specifications, these dowel pins ensure reliable fixation of rail clips to concrete or wooden sleepers, reducing maintenance costs and enhancing operational safety. Backed by our factory warranty support, each pin is crafted with precision and tested for consistent performance under heavy loads and extreme weather conditions.
Our dowel pins are manufactured in our Hebei-based facility, which annually exports US$5 million to US$10 million worth of products to global markets including North America, Europe, Southeast Asia, and Africa. We utilize advanced cold heading and heat treatment processes to achieve superior tensile strength and dimensional accuracy. The product is available in various diameters (20mm–40mm) and lengths (100mm–300mm), with surface treatments such as hot-dip galvanizing, black oxide, or plain finish to suit different environmental requirements.

Our railway sleeper dowel pins are designed to withstand dynamic loads from passing trains, constant vibration, and environmental corrosion. The helical/shank design (optional) increases pull-out resistance, while the chamfered ends facilitate easy insertion into sleeper holes. Unlike generic fasteners, our pins are manufactured strictly to standard dimensions, reducing the risk of installation failure and track misalignment. Clients benefit from reduced downtime, lower replacement frequency, and improved overall track stability.
We have supplied dowel pins for major railway projects in North America, Europe, and Southeast Asia. Our factory's annual export value of US$5 million–US$10 million reflects the trust of global buyers. With shipment ports including Tianjin, Qingdao, Shanghai, and Foshan, we ensure timely delivery worldwide. All products undergo rigorous quality checks: dimensional inspection, hardness testing, and pull-out force validation. We provide free samples for evaluation, and our engineering team supports custom designs based on your sleeper specifications.
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a reliable partner in the hardware and railway fastening industry.
